The midi-in is receiving the signal, but the instrument is not activated

[quasilyte]

Hello. I'm just starting to learn drumming and using Hydrogen, but I'm a confident Linux user. I have an issue that I failed to Google of find via an issue search (mostly because it's hard for me to tell what exactly is going wrong here).

• I have a Roland TD02kv electronic drum
• It's connected via the USB to the Linux Mint laptop
• I'm using the Hydrogen 1.1.1 dev build
• I'm using the qjackctl to connect the TD-02 midi as the hydrogen input

Problem: the Hydrogen ignores the hi-hat instrument more often than not. I see the midi-in indicator in the top part of the Hydrogen main UI flickering, as it's receiving the input, but the instrument is not triggered.

It doesn't matter how hard I hit the hi-hat.

I think I either need to debug a MIDI stream to see what messages does the Hydrogen receive or maybe I need to configure the Hydrogen to handle these messages correctly.

Here is the qjackctl screenshot:

The Hydrogen clearly getting some sort of an input from the drumkit:

But the instrument is not triggered. I see no sound, and the relevant icon isn't flashing inside the mixer:

If I get lucky, sometimes it's activated, but the sound looks reduced or whatever:

Observation: only one part of the hi-hat is being this tricky. If I hit the back part of the pad, it plays 100% of the time.

Another weird thing is that there is a ~100% chance that the hi-hat instrument will be triggered IF I trigger some other instrument right before it. But if I go on with a hi-hat alone after that, it will eventually start to ignore it after a 3 or 4 hits.

I thought that it could be related to the note-off setting, but switching it off doesn't help here.

These are the settings I'm using:

I tried using the TD2 as an input device; the results are the same.

What do you know, there is more than one Hydrogen project on the GitHub and this one appears closer to the top of the results lol. This is the wrong repository for me, sorry.
